植物病原体Embellisia adsurgens引起一种称为黄矮病和根腐病的疾病，在站立的紫云英（沙打旺）。2013年，Embellisia和12个近似属被重新定义为与Alternaria同义。然而，该分类修订没有包括E。- 是的本研究的目的是确定该真菌种的分类地位，通过比较其形态和分子特征与其他物种。基于GPD、RPB 2和TEF-1 3个基因座的序列构建的系统发育树支持E.链格孢属链格孢组（Alternaria sect. Undifilum）该菌在马铃薯胡萝卜琼脂上也表现出芽管和菌丝体的“波浪状”外观，这是Undifilum组的特征。在此将Emellisia gansuense comb. nov.描述为Alternaria gansuense comb. nov.，因为种号““已经被占用。
The plant pathogen Embellisia astragali causes a disease termed yellow stunt and root rot in standing milk-vetch (Astragalus adsurgens). The genus Embellisia and 12 allied genera were redefined as being synonymous with Alternaria in 2013. However, that taxonomic revision did not include E. astragali. The objective of this study was to determine the taxonomic status of this fungal species by comparing its morphological and molecular characteristics with those of other species. A phylogenetic tree developed based on the sequences of 3 loci (GPD, RPB2, and TEF-1) strongly supported the placement of E. astragali in Alternaria sect. Undifilum. The fungus also exhibited germ tubes and mycelia with a 'wavy' appearance on potato carrot agar, which is a characteristic of sect. Undifilum. Embellisia astragali was described here as Alternaria gansuense comb. nov. because the species epithet "astragali" was already occupied.
